gosh.. the answer is the inner planets; mercury, mars, earth, and venus.
the sun was bigger and brghter then gave birth to four gas planets then rocky ones and probable give birth again our system is getting larger the planets lining up just might do that 26000 104000...
this is because the cores of those rocky planets are made out of rocks technically.Hope that helps
In our solar system, there are officially 4 rocky planets: Mercury Venus Earth Mars The small dwarf planet called Pluto is also rocky.
The four inter. Plants are rocky and the other plants are gases
